RV Battery Types – The Basics

RV Battery TypesRV batteries are used for many applications, including on coffee makers, water pumps, microwave ovens and blenders, among other appliances. But then, there are many kinds of RV batteries, so you need to know about each of them in order to find the best one. In the following, we’ll talk about the common types of RV batteries that you can compare and choose from for use in your rig. Find the three main types of RV batteries. But under deep cycle batteries, you will find four types, each with its characteristics. Before buying one, find out what makes each unique and specific for your needs to come up with a good buying decision.

Starting batteries

What makes starting batteries unique is that they work using a number of thinner plates, which are able to maximize the surface area being exposed to the electrolytes, providing high amounts of energy working in short bursts. They’re rated based on cold-cranking amps. What are these? They’re the amps number that one battery can supply at 0 degrees F for a period of 30 seconds without dropping below only 7.2 volts.

In this case, these batteries must not be used for RV deep cycle battery uses. You should know its ways of workings if you’re deciding to buy one for your rig and maximize its use and efficiency.

Deep Cycle batteries

Deep cycle cells or batteries have varying sizes, with larger ones supplying more amps to your rig. So when it comes to choosing one, you must determine your power requirements as well as the space available in your RV to select and install the right one.

At the very least, a deep cycle battery is a lead-acid type that is designed for deep discharging by using most of its intended and specific capacity. Some of them can be used as a starting battery; however, take note that the lower cranking current power indicates that a larger battery is needed. Usually, deep cycle types are subdivided into several groups or types that we’ll discuss in the following sections:

  • Flooded Lead Acid Deep Cycle Batteries

    A flooded lead-acid type is also called wet cells. It is notable for its flooded appearance due to the electrolyte fluid surrounding the plates, which have to be submerged totally. Its use originated from a lead-acid chemistry discovery made by Gaston Planté in 1859.

    This type is the most common and popular among deep cycle batteries used by RV owners for their rig. The electrolyte is a mixture of water and sulfuric acid surrounding the lead-oxide and lead plates. Flooded types deal with overcharging better than AGM or gel deep cycle batteries because they’re unsealed and due to their hydrogen venting system.

  • AGM Deep Cycle RV Batteries

    AGM deep cycle lead-acid batteries are applicable for many applications, such as in boats, trolling motors, trucks, campers, travel trailers and recreational vehicles. They’re also better than flooded batteries because they don’t need frequent maintenance. These batteries are also tougher and stronger than other types of deep cycle batteries.

    These batteries also have a different design from a flooded deep cycle battery. Here, the electrolyte is in the glass mats, not flooding the plates freely. AGM batteries have thin glass fibers attached or woven into a mat, holding enough electrolytes due to the increased surface area.

  • Deep Cycle Gel Batteries

    Gel batteries are also popular among RV owners because they’re easy to transport and move around than other types are. However, they also offer the same benefits over the flooded types. Gel deep cycle batteries are preferred by those who are planning to use their batteries in tougher situations and places with high vibrations and temperatures.

    However, these batteries are more expensive than an AGM battery even if they might have the same battery capacity. Gel types are not also recommended if you don’t have enough experience working with battery chargers and batteries. But in general, the gel deep cycle battery is used in solar power uses.

  • Lithium-ion Deep Cycle Batteries

    For a better battery, the lithium-ion type is chosen by recreational vehicle owners due to its supreme performance far better than AGM or flooded lead-acid batteries. This type is also advantageous for those looking to use a lighter battery type offering a charging efficiency reaching up to 5000 life cycles.

    Most RV owners also pick the lithium battery because of its steady performance under extreme temperature conditions, such as cold and heat. In addition, the deep cycle battery is very efficient even when running at low temperatures. In fact, it can also operate safely in a place where the temperature is up to 149 degrees Fahrenheit. In addition, it offers versatile mounting, providing consistent energy flow in any direction throughout its use.


Dual Purpose or Marine

A dual-purpose battery can offer supreme starting power together with cycling capabilities. It is also used with a switch system or an isolator, functioning as a backup for a deep cycle house battery or starting battery. Dual-purpose or marine batteries can handle starting and cycling, but then, most of them will not be able to start an engine when compared to a true cranking battery. It might not also be able to handle numerous discharges and recharges when compared to a real deep cycle battery. Take note of these things before deciding to buy a marine battery for your rig.

What voltage is a RV battery?

First, what is voltage? It’s the pressure coming from a power source’s electrical circuit, pushing the current of charged electrons through a conducting loop. Following you can illuminate a light or supply power to your recreational vehicle electronics. Now in order to understand voltage better, remember that RV batteries are running on a 12V DC power deep cycle electrical energy, although does not apply to all.

When choosing an RV battery, consider the amount of power you need for your rig. So before you choose a deep cycle battery to discharge and recharge repeatedly without damaging the battery know what voltage rating is available.

12v RV Battery

This RV battery system lets you operate a computer, TV, microwave, lighting & other types of electrical appliances. It is also used in charging some systems present in your recreational vehicle that is using 12V power. A 12V system also works in a parallel connection in order to maintain a continued 12V connection.

In most cases, you will see them with two jumper connections, which work to keep the 12V system. Why you might want to use a 12V RV battery? It gives out double the amp hours, consistent 12 volts power, is easy to buy in auto parts stores, and is less expensive versus the 6V type. The drawback, however, is a much less amp-hour rating for each battery.

6v RV Battery

Generally, it is a golf cart battery, one of the most versatile and useful batteries for someone living off the grid. The 6V battery system is also chosen by small home or cabin owners. The 12V models are also chosen by many campers or travel trailer owners. It all boils down to your personal preference and power needs.

One difference it has with the 12V battery is that it operates in a series connection to achieve a 12V system required for your recreational vehicle. For their pros, these batteries have a larger amp-hour capacity, longer lifespan with good maintenance, and greater discharge and recharge capacity. The only problem is that its initial cost investment is much expensive than the 12V models are.

When trying to compare, you might be asking why to choose one over another battery. That is a good start. If choosing between 6- and 12-V systems, you should remember that 6V types are larger but lighter only about 45lbs versus a 12V type that’s about 100lbs.

Today, many RV owners are upgrading to 6V systems for a single power source. For one, the series connection tends to last longer while at the same time supplying double the voltage. Also, 6V systems tend to last longer because of more space for each cell and thicker plates. But then, going for 12V systems will give you twice the amp-hours and voltage. Definitely, both types have their pros and cons. To choose well, determine your power requirements and RV space you have.

Which RV Battery Is Best?
